Does Blender offer 64 bit processing?

I am impressed with Blender so far.

No it doesnt at the moment. Im not sure what we would have to do to get it supported either. I was wondering if we could just use a 64 bit compiler or whether we would need to change the code considerably.

64 bit for 3D apps would be sweet.

Hi,

this is not possible because of C and C++.
By definition the size of an int is the size of a void * which is by definition dependant on the system. So on a 32-bit system, an int is 32 bit, on a 64-bit system this would be 64 bit.
You can imagine all the problems we will encounter.

With regards,
Michel

Hi,

explain to me, please, what the advantages would be for 64 bits over 32 bits?

With regards,
Michel

Michel: If people code in C/C++ properly (ie: cross-platform, with Blender is) than a 64-bit binary could be made as easily as just recompiling the source in 64-bit mode.

Requirement to use a 64-bit app: A 64-bit processor and OS! So if you are a windows user, you're out of luck right now. Linux has had this for some time though.

Advantages: You'll be able to run Blender on a 64-bit CPU and OS? Take advantage of the 64-bitness of the CPU for more bandwidth across the board?

Wasn't Blender's original SGi version 64-bit? I seem to remember reading that somewhere...

I think a lot of people may be wondering about this because of AMD's intorduction of their 64 bit processor. I believe that Microsoft is planning a 64 bit OS version. It may be a good idea for the Blender community to give serious consideration to compiling a 64 bit version. Others (software that is) may be planning to do the same.

Don't forget about Mac OS X and the G5 processor (IBM PowerPC 970). Although OS X is not a fully 64 bit OS yet (for compatability) it does support >4GB of RAM and 64-bit integers.

There are advantages to having a 64 bit version of Blender available, most people will never notice the difference though. The bigest benefit will be perception, a lot of people think that 64 bit processing is the greatest thing ever... they don't care that they can't (yet) get much advantage from it.

Who cares about a 64 bit version of Windows when we already have linux?!

hem, if blender run on Irix, what do you conclude?? :p

a 3D Program or Renderer manipulates what? floats
and what's the advantage of 64bits?
well, i let you think about it

in clear, it will be a great BOOST

Answer: 64 bit floats, as opposed to 32 bit floats.

64 bit xp available from M$ for testing

And you need 64-bit drivers to get it going too. Sucks. Linux has had this ability for some time, and is a hell of a lot more mature.

Windows? Who cares about windows.
